Carb Caps are a must for low-temperature dabbing. Using a carb cap will allow you to fully vaporize your concentrates at the lowest temperatures possible for smooth flavorful hits. The angled hole positioned on the edge of the High Five Deep Dish Titanium Nail Carb Cap produces a vortex inside the dish of the nail. This vortex pushes your concentrate around the nail for maximum vapor production. The High Five Deep Dish Titanium Nail Carb Cap will also stop your oil for pooling in one side of the nail so non of your material is wasted. The High Five Deep Dish Titanium Nail Carb Cap fits both 16mm and 20mm dishes.
